Why does this have two different code paths for the
"unlink everything that the hardware doesn't have its
mittens on" branch?
Exactly because this cases needs to be handled differently. Re-read
the patch description please.
It certainly *looks* goofy this way, and if it's not
What *ceartainly* looked goofy is the "code" that was there before
this patch.
buggy today then it'll probably grow some in the future.
